Language barrier?

At the bank today, there was an Asian lady who was trying to exchange yen for dollars. It was obvious that she was a little irritated...

She asked the teller, "Why it change? Yesterday, I get two hunat dolla fo yen. Today I only get hunat eighty? Why it change?"

The teller shrugged his shoulders and said, "Fluctuations."

The Asian lady says, "Fluc you white people too!"
